Verbena plant named ‘Lirosena’

ABSTRACT

A new and distinct variety of  Verbena  plant particularly distinguished by its lilac-rose flower, early flowering and a habit that is semi-erect.

Latin name of the genus and species of the plant claimed:Verbena×hybrida.

Varietal denomination: ‘Lirosena’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Verbena,botanically known as Verbena×hybrida.

The new cultivar is propagated from cuttings resulting from the cross of‘C1039’ and ‘A715’. ‘C1039’ is a lilac flowering Verbena having aspreading habit. ‘C1039’ is not commercially available and is not knownby any synonyms. ‘A715’ is a rose flowering Verbena having a trailinghabit. ‘A715’ is not commercially available and is not known by anysynonyms. Neither ‘C1039’ or ‘A715’ has been patented.

As a result of this cross the present cultivar was created in 2000 inEnkhuizen, Netherlands and has been repeatedly asexually reproduced bycuttings in Enkhuizen, Netherlands and Sarrians, France over a threeyear period. It has been found to retain its distinctive characteristicsthrough successive propagations, and this novelty appears to be firmlyfixed.

This new Verbena plant is an annual in most climatical zones in the US,only in zones 9 and 10 it is a perennial plant.

DESCRIPTION OF THE DRAWING

This new Verbena plant is illustrated by the accompanying photographicdrawing which shows blooms, buds and foliage of the plant in full color,the color shown being as true as can be reasonably obtained byconventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctivecharacteristics of this new Verbena. The data that define thesecharacteristics were collected from asexual reproductions carried out inEnkhuizen, Netherlands. The plant history was taken on 14 weeks oldplants, blossomed under natural light in a greenhouse and grown in a10.5 cm container. Colour readings were taken in the greenhouse underambient light. Color references are primarily to The R.H.S. Colour Chartof The Royal Horticultural Society of London.
